In December, nosotros launched several new Intelligent Answers that go beyond the traditional Q&A style of search and offer answers to more complicated questions. We received and so much interest in providing multiple perspectives to an answer, that we wanted to share more than details on how information technology came about and what we are doing to make it possible.

I'm a large yoga fan and have been practicing it for years. A few months ago, I decided to effort hot yoga for the first time. When I got to the studio, I noticed that the temperature was manner hotter than expected, and I forgot to bring a water canteen.

The course was amazing, just I felt dizzy and lighthearted. I couldn't help but wonder… is hot yoga practiced for me?

I decided to Bing my question to learn more about it. At the very top, Bing had the following respond:

"Why Hot Yoga? There are countless benefits for those who incorporate hot yoga in their lives. Nosotros like to think of it as a 'work in' as opposed to a 'piece of work out'. The reason being that someone who practices yoga consistently will discover the changes on the outside occur first, such as weight loss, muscle toning and even clear, radiant peel."

This was proficient. I rapidly received an reply confirming that hot yoga was a healthy sport from a relevant site. But I knew at that place might be some drawbacks for hot yoga as well. I repeated my search equally {is hot yoga bad for y'all} and got another answer, this time showing that hot yoga could be dangerous.

That's when information technology struck me: There are many questions that don't have just 1 answer, but multiple valid perspectives on a given topic.  Should I repeat my search with the give-and-take "bad" or "expert" in information technology every time I wanted to become a comprehensive picture of a topic and hear the other side?  How would I even know how and when to do that? Should I assume that this single answer Bing returned for me was the best or the only answer? Is that the well-nigh administrative page to answer my question?

How exercise we solve this problem?

Search results are often limited to many bluish links and sometimes one link and snippet of text highlighted at the tiptop. Just there are many questions where getting but one point of view is not sufficient, convenient or comprehensive.

Many times, you desire to hear different perspectives, points of view and opinions about a question you lot have. Today, when yous utilize a search engine to notice answers to your questions, your experience can chop-chop turn into an echo chamber because search results ofttimes cover only one side of the spectrum of possible answers to your questions, which can lead to "confirmation bias."

As appear at the Microsoft AI upshot in December 2017, we believe that your search engine should inform y'all when there are dissimilar viewpoints to respond a question yous take, and it should assistance yous save inquiry fourth dimension while expanding your knowledge with the rich content available on the Web. Therefore, we congenital a new experience for you.

Endeavor "is hot yoga good for you" today and yous volition now see both perspectives.

Clicking on the right-hand side helped me learn that I need to beverage lots of h2o, stretch properly and encompass the yoga mat with a towel to avert breeding germs on it.

How does Multi-Perspective QnA work?

Based on processing billions of queries and spider web pages, Bing intelligently understands when your question or topic of involvement has diverse valid perspectives and tin can show you lot snippets explaining those opinions from passages or brusque blurbs of text extracted from many different websites. Thus, nosotros tin at present go along you well-informed on topics that have opposing viewpoints. Using several different models in combination, we prioritize reputable content from authoritative, loftier quality websites that are relevant to the subject area in question, take easily discoverable content and minimal to no distractions on the site.

When yous issue a search query like "is coffee skillful for you", passage candidates from web pages are selected based on our powerful Spider web Search and Question Answering engine. After that, we build clusters over the passages to determine similarity and sentiment using deep recurrent neural network (Deep RNN) models. Lastly, we rank the well-nigh relevant passages from each cluster based on sentiment analysis and several other features, to deliver you the nearly relevant results from web sources. This process is summarized in the following image.

One of the key challenges in this projection was edifice the Deep RNN since existing country of the fine art sentiment classifiers were limited in their ability to excerpt the correct sentiment from web passages. For example, take the passage below:

"You could burn down more than fat. Caffeine is plant in most every over-the-counter fat-burning supplement commercially bachelor today. And for proficient reason. It's been shown to increase metabolism past 3 to 11 percent, and to increase the burning of fat from ten to 29 percent, depending on your body type."

Existing classifiers would written report that the passage had a negative sentiment since at that place are words such as "burn" and "fat". Withal, our deep neural network-based models are specifically built to handle spider web data. Equally a issue, they correctly observe that the passage higher up has a positive sentiment: information technology describes the benefits of coffee.

So, when you search "is coffee salubrious" on Bing, we testify you passages as search results that offer y'all two different perspectives on this topic instead of just one side. This allows y'all to meet this topic from multiple viewpoints, enriching your understanding and allowing you to course your ain stance.
